SpaceX CEO Elon Musk says that Crew Dragon – originally designed to propulsively land like Falcon 9 – is still technically able to do so, a capability that could give the already uniquely redundant spacecraft yet another level of safety during Earth reentry and landing.

While Musk noted that adding or enabling that capability during missions with astronauts would be entirely dependent upon NASA’s approval, the idea would be to trigger Crew Dragon’s SuperDraco abort thrusters in the event of a partial or total failure of the spacecraft’s parachutes. Although Crew Dragon is already capable of keeping its passengers safe if one of its four parachutes fails to properly deploy, the loss of any additional drag would likely create a situation where the force of impact on the ocean surface could severely injure or kill astronauts, much like a car crash without airbags. To prevent this, Crew Dragon could fire its thrusters at the last second, canceling out or at least minimizing the force of impact.

If it can be done, Crew Dragon would be the only spacecraft in the world with the ability to ensure crew survival in the event of a failure involving parachute deployment, although it’s not clear if that recovery redundancy would still be available after an actual in-flight or pad abort during launch operations. Still, for a space agency so apparently fixated on and worried about ‘qualifying’ SpaceX’s Crew Dragon parachutes and a “Safety first!” culture more generally, one would expect NASA to jump on any opportunity to dramatically improve spacecraft safety with minimal additional effort.

Thanks to SpaceX’s decision to permanently integrate the SuperDraco-powered launch abort system (LAS) into the capsule itself, compared to most other solutions with ‘escape towers’ or service section-based abort systems ejected once in orbit or prior to reentry, Crew Dragon can escape from Falcon 9 at any point from the pad to orbit. Boeing’s Starliner capsule also features this capability, although its abort system is integrated into its trunk, which – like Crew Dragon – is detached before reentry, meaning that Starliner would have little to no control authority during descent and recovery aside from small maneuvering thrusters. For Starliner, the potential consequences of a parachute failure during recovery are quite a bit higher than Dragon as a result of Boeing’s decision to land the capsule on land, a process that actually necessitated the inclusion of a complex series of additional deployment events for a successful (and safe) landing.

During Starliner landings, the capsule must deploy its drogue chutes and main parachutes (three instead of Crew Dragon’s four), but also has to eject the entire heat shield section and deploy airbags shortly before touchdown. If one or all parachutes failed to properly deploy, Starliner would have no recourse to protect its passengers, while a failure of heat shield deployment or airbags likely would result in significant damage to the spacecraft and potentially injure the crew. While it adds complexity, many other spacecraft – including Russia’s Soyuz capsule and Blue Origin’s New Shepard capsule – rely on actively-cushioned land recoveries, although they typically use small thrusters (usually solid rockets) instead of cushions to achieve a softer touchdown.

Still, the fact that Crew Dragon will likely approach its splashdown with several thousand kilograms of propellant still aboard and (nominally) unused SuperDraco thrusters clearly offers a major opportunity for added redundancy and safety, potentially requiring little more than a software update to enable. If possible, the opportunities stretch well beyond simply cushioning anomalous ocean splashdowns, potentially allowing for abort scenarios where Crew Dragon would be able to safely return crew to Earth even in cases where the capsule would be forced to land on the ground by using its SuperDracos to cushion what would be an otherwise dangerous crash.

According to SpaceX CEO Elon Musk, the company may actually explore – if not operationally utilize – the capabilities lent by Crew Dragon’s (also known as Dragon 2) abort thrusters, including redundant recovery and propulsive or cushioned landings at sea or on land. SpaceX is set to use refurbished and slightly modified Crew Dragons to fulfill its second Commercial Resupply Services (CRS2) contract with NASA to deliver supplies to and from the International Space Station (ISS).

Why SpaceX is finishing another space-internet system that isn’t Starlink

SpaceX launched three final O3b mPower satellites Sunday, finishing a lesser known SES satellite network.

Published

on

By

SpaceX had an 87 minute window opening at 2:49 p.m. Eastern on Sunday to fly a Falcon 9 out of Cape Canaveral carrying the final three satellites for SES’s O3b mPower constellation, a project that has taken more than a decade to finish since Boeing and SES first signed SpaceX on for the work.

Unlike the thousands of Starlink satellites SpaceX has stacked into orbit over the years, O3b mPower flies in a different neighborhood entirely. The three new satellites, tagged F11, F12 and F13, are headed for medium Earth orbit at roughly 5,000 miles up, more than ten times higher than Starlink’s shell around 340 miles but still a small fraction of the 22,000 miles where old school geostationary satellites sit. That middle position is the whole point, because a satellite that far out needs far fewer siblings to blanket the globe than a low orbit constellation does. Essentially, SES only needed 13 satellites total to build a network offering quick, steady service that used to require thousands of spacecraft.

With most people having heard plenty about Starlink and almost nothing about O3b mPower, SES and SpaceX already blend the two networks for some customers. Both SpaceX and SES sell satellite broadband, but they’re aimed at different buyers. Starlink is built for volume, direct to consumers, RVs, homes, small businesses, plus a growing aviation and maritime business. O3b mPower skips consumers entirely and sells enterprise grade connectivity to airlines, cruise lines, offshore energy operators, telecoms needing backhaul, and governments, priced and provisioned more like a dedicated circuit.

A 2023 partnership lets cruise ships combine Starlink’s speed with O3b mPower’s steady capacity depending on what a ship needs at a given moment. Sunday’s completed 13 satellite constellation effectively finishes the medium orbit half of that pairing, years after.

Sunday’s mission was already a something on SpaceX’s manifest well before O3b mPower entered the picture. This flight marked its 29th trip to orbit, a history that includes two crewed Axiom missions, the European Space Agency’s Euclid telescope and 22 separate Starlink batches. SpaceX has landed boosters on the droneship A Shortfall of Gravitas so often that Sunday’s touchdown attempt, if it went as planned, was set to be the 661st successful Falcon booster landing to date.

For a company that pushed the Starlink constellation past 11,000 satellites back in August, almost entirely through bulk launches from California, Sunday’s flight was a reminder that SpaceX’s schedule still has room for someone else’s satellites too. SES gets a finished network built for a narrower set of customers, and Falcon 9 gets one more line on an already long resume.

Tesla gives the Roadster an official “Go for launch” demonstration date

Tesla teased an October 1 Roadster reveal, reviving years of delayed SpaceX thruster hover promises.

Tesla teased an October 1 event date for its next generation Roadster, posting an image on X Saturday that shows the car lit up like it is sitting on a launch pad, with the date “10.01” stamped across the bottom and the caption “Go for launch.” A countdown clock on Tesla’s Roadster order page now points to the same date, which falls on a Thursday. The company has not said where the event will happen or whether it will be streamed at the moment. Stay with us @Teslarati for live updates.


Tesla has since sent formal invitations to reservation holders confirming the event will take place in Waco, Texas, about 90 minutes north of its Austin headquarters, based on a digital ticket shared on X by Sawyer Merritt. Tesla did not name the exact venue, though Waco sits close to SpaceX’s McGregor, Texas, rocket test site, previously reported as the planned location for a Roadster thruster demonstration. The invite sets the reveal for 8:30 p.m. Eastern on October 1, requires RSVPs by midnight on September 16, and limits entry to guests 21 and older. Invitations are non-transferable.

The tease follows nine years of a project defined by unimaginable specs along with slipped dates. Musk first showed the second generation Roadster in November 2017 as a surprise reveal at the end of the Tesla Semi event, promising a 0 to 60 mph time under two seconds, a top speed above 250 mph, 620 miles of range from a 200 kWh battery, and production starting in 2020. At last November’s shareholder meeting, Musk set an April 1 demo date and joked the choice gave him “deniability” if it slipped again, which it did, moving first to late April, then to “a month or so,” then to August.

Whatever Tesla shows on October 1 is expected to center on the SpaceX developed thruster package Musk has described since 2018. Internally code named A71, a nod to the Lockheed SR-71 Blackbird, the system reportedly uses cold gas thrusters fed by a composite overwrapped pressure vessel, the same tank design SpaceX uses on Falcon 9. Musk has said a thruster equipped Roadster could hit 60 mph in about 1.1 seconds under roughly 2.75 g of launch force, well past the 1.9 second figure quoted for the standard car. That version reportedly will not be street legal and has reportedly been discussed as a limited run sold through a track only program.

The standard Roadster is still expected to carry the original $200,000 base price and $250,000 Founders Series tier, both set when Tesla opened $50,000 and $250,000 reservations in 2017. Tesla VP of Vehicle Engineering Lars Moravy has confirmed production will happen at Gigafactory Texas, with Musk targeting 2027 or 2028, 12 to 18 months after whatever the company demonstrates next month.

SpaceX tells the FCC that Starship Flight 14 is going to orbit

SpaceX filed with the FCC for Starship Flight 14, its first true orbital launch attempt.

Published

on

By

SpaceX has asked the Federal Communications Commission for permission to fly Starlink terminals during Starship’s fourteenth flight test, and the filing lays out a genuine trip to orbit, something the program has never attempted.

Every Starship flight so far, including Flight 13’s successful splashdown in the Indian Ocean on July 24, has flown a suborbital arc that ends with the ship reentering the atmosphere within the same hour it launches. The FCC paperwork describes a mission profile built around an actual orbital insertion instead.

The payload is the other half of the story. Flight 13 carried 20 production Starlink V3 satellites, but because that mission never reached orbit, the satellites reentered along with the ship rather than joining the constellation, something Teslarati covered in detail after SpaceX released footage shot from one of those satellites as it drifted away from Starship in space. Flight 14 is designed to close that gap. If the orbital insertion holds, the roughly 20 V3 satellites onboard would separate into an operational orbit and could eventually go into service, each one rated for about 1 terabit per second of downlink capacity by SpaceX’s own account.

SpaceX announces new Starbase for ‘thousands of Starship launches annually’

Elon Musk first flagged the orbital attempt during SpaceX’s August 4 earnings call, the company’s first as a public entity following its June IPO under the ticker SPCX. He also floated catching the ship with the Starbase tower on the same flight, an idea he walked back on August 20, saying the catch attempt would more likely come “in a few months,” as Teslarati reported at the time. Flight 14 will instead target a splashdown for the ship in the Indian Ocean, the same recovery method used since Flight 12.

Hardware has been catching up to the ambition. Booster 21 completed a full 33-engine static fire on August 28, and Ship 41 finished its own six-engine test the week before. An airspace briefing circulated to pilots on August 20 listed September 15 as the target date, later than the end of August window Musk mentioned on the earnings call, though SpaceX has not confirmed a launch date publicly and Starship schedules routinely slip while hardware and FAA paperwork line up.

The FCC filing itself does not guarantee a launch date. It covers communications authority, and not flight readiness, considering SpaceX still needs Ship 41 fully stacked and cleared by the FAA before Flight 14 can fly. But the filing is a real marker of intent and it puts a specific regulatory process behind what had so far only been Musk’s word on the earnings call.
